Description: This experimental device provides six LED display circuit 8 code, students will address output by the corresponding data can be achieved on the control display. Shows a total of 6, with the dynamically displayed. 8-bit code segment, 6-bit code output by two 74LS374. Bit code by the MC1413 or ULN2003 inverter drive, select the appropriate display position. The experimental device in 8-bit code segment output address 0X004H, bit code output address 0X002H. Where X is the KEY/LED CS decision, see the address decoding. Do keyboard and LED experiment, take the KEY/LED CS on receiving the appropriate address decoding. In order to use the appropriate address to access. For example, KEY/LED CS received CS0 on the section of code address is 08004H, bit code address is 08002H.
